Second harmonic generation in germanium quantum wells for nonlinear silicon photonics

Jacopo Frigerio, Chiara Ciano, Joel Kuttruff +12

Second-harmonic generation (SHG) is a direct measure of the strength of second-order nonlinear optical effects, which also include frequency mixing and parametric oscillations. Nat…

THz intersubband electroluminescence from n-type Ge/SiGe quantum cascade structures

David Stark, Muhammad Mirza, Luca Persichetti +15

We report electroluminescence originating from L-valley transitions in n-type Ge/SiGe quantum cascade structures centered at 3.4 and 4.9 THz with a line broadenin…
